Answer: B
Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.

Answer:
Step-by-step explanation:
We have been given that the ages of the winners of a cycling tournament are approximately bell-shaped. The mean age is 28.7 years, with a standard deviation of 3.7 years.
To transform the age of a 22 years old winner to a z-score we will use z-score formula.
, where,
,
,
,
.
Upon substituting our given values in z-score formula we will get,
Therefore, the z-score corresponding to the age of a 22 years old winner is -1.81.
